WATERVILLE, Maine — The Department of Defense says the soldier from Waterville who died Thursday in Jaghatu, Afghanistan, was killed by indirect fire from a rocket or mortar fired by insurgents.

The Morning Sentinel of Waterville reported Sunday that 21-year-old Army Spc. Wade Slack worked in combat, performing duties depicted in this year’s Academy Award-winning film for best picture, “The Hurt Locker.” But officials said Slack did not lose his life in an accidental detonation while working to disarm a bomb.
